T 0 all whom 2'6 mm! concern:

Be it known that we, SAMUEL E. AUTREY and Josnrii ii, llli'rcHELL, citizens of the United States, residing at Sherman, in the county of Grayson and State of Texas, have invented certain new and useful Improvements in Gas Generators and Burners, of which the following is a specification.

This invention relates to a combined gas generator and burner for kerosene oil, and it particularly relates to a device of this character adaptedto be employed in connection with ordinary cooking and heating stoves, furnaces, and the like, or for divers other purposes.

An object of the invention is to provide a device of this character which may be fitted into the fire-box and seated upon the grate ot' stoves of diiierent sizes, and which shall be comparatively simple, durable, and inexpensive in its construction, as well as being practical and efi'icient in op oration.

A further object of the invention is to provide a burner embodying a retort in con nection with a superheating pipe vvhereby the retort, in hein heated, will vaporize or gasify the liquid tuel in order that the gas or vapor may be heated to a high temperature in the superheater pipe, and a most effective combustion of gas result to produce a maximum heating etiect with a minimum expenditure or" fuel.

This invention also embodies various subordinate features oi construction and combinations of parts, all subservient to the broad features above outlined, which will be more fully described hereinafter, illustrated in the accompanying drawings, and finally pointed out in the claim iereunto pended, it being understood toat changes in the precise embodiment of the invention herein disclosed canbe node within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred i'orxn in the accompanying draw iii-gs, wherein Figure l representsa front elevation of a stove with the burner applied, portions being broken away. Fig 2 is a plan view of enlarged detail view of one of the retorts removed.

Referring more particularly to the in which similar reference numerals designate corresponding parts throughout Patented Mar, i l, 191% Application filed July 26, 1915. Serial No. 42,001.

the several views, 1 indicates a stove or" ordinary construction and 2 the usual grate bars thereof. A suitable rectangular base 3 is seated upon the grate bars and extends longitudinally nearly the length of the firebox a. A pair of cylindrical retorts, 5 and 6, are seated upon the base, one near each end tiereof, and centrally located and secured to the bottom of the retorts are tubes 7 8 that extend upwardly Within them for about two-thirds their height, and downwardly through their bottom ends, also, through apertures in the base 3, Where ' elbows 9 and 10 are attached thereto; the downward projecting ends of the tubes being of the proper length to permit the connected ends of the elbows to rest adjacent to the under side of the base 3, and thus serve to retain the retorts securely in nosition upon the base. To the other ends of the elbows 9 and 10 are connected oil supply pipes 11 and 12, that are disposhd horizontally beneath the base, to and throughi an opening in the door at the opposite end of the stove, whence they branch laterally as shown at 13 and i l, and are fitted with the usual angle oil supply valves 15 and 16, which valves are in turn connected with the top side of a laterally disposed oil receiver 1?, through vertical check valves 18 and 19,

The retorts 5 andfiare filled with small as, tor instance, screws clown,

deflectors or spreader-s 28 and 29, centrally located ov r the gas gets and apt-ed to spread the flame when the (an said jets is burning. Small lras w res 539 are *osed within the superheating pipes to 51st in heating the va'oo r a,

'herethroug '1 the pebbles in the carbonaceous matter, should be m iled in the process oi converting the 'i'JGl into 31. and 33?, renresent rnnin ans bndm i e a g; intents ing openings 33 and 34: extending through the base 3, beneath the jets 26 27 seicl puns may have a layer of asbestos therein to absorb the oil primarily required to start the burners,-the oil being, ignited therefrom. A fuel supply tuuk 35 may be sup ported in any convenient manner above the level of the burners and connected with the bottom side of the reservoir 17, by a pipe 36. in operation, liquid fuel, such as coal oil, or the like may be fed by gravity or under pressure, from the supply tank, through the supply pipe, and. check valves, Where the quantity thereof is regulated by the valves 15 and 16, and the oil continues its course thence and flows through the pipes 11. anal 12, and initially, to the retorts 5 and *5, through the superheating and burner sections, and out through the jets 36 end 27 and partly fills the priming pens 31. and. I 2-, whereupon. the supply is out off by means of the valves and. the fuel Within the ignited, thereby heating the I'EiOlijS and pipe sections to such an that if the oil is again. admitted the heat upon the retoits zinc. sections quickly converts the oil therein into gas, and the burning of the gas from the jets keeps the retoi'ts and pipe sections continually hot enough to continue the genemf-ion of gas so long as fuel is admitted through the pipes. W hen the pri nary chergmg supply of oil is consumed, oil will er only slowly ooze frezn the tubes .i 8, to the pebbles contained 111 torts which being very hot, vupoi'izes the by Letters Patent of the Unitecl States, is-- in a gas generator and burner for stoves and the lihcyu base, a retort at each end of the base and supported thereby absorbent materiel and an upstanding tube in each retort, said tubes connected. through the bottom ends of the retorts to liquid. fuel. supply pipes, e pipe connected with the to of each retort that comprises superheeting and burner sections, the letter having e jet e ening therein, and means for supplying liquid fuel to the i'uel supply pipes, as set ioi'th, In testimony whereof We ailix our SlgMt tures in presence of two Witnesses.
